Re: the disney channel
I believe there is a channel you can buy called Toon Disney...it's got the old stuff like Aladdin, Lion King, Tarzan, or at least such that have been made off of movies.
Meh, I just recently got cable, about three years ago, so this "old Disney Channel" you speak of doesn't register well..~.~ Though I wouldn't mind seeing them, Tales of Avonlea sounds...cool.
As for why teen shows, they're trying to appeal to the pre-teen age. Hence, in order to do this, they do the whole teenager thing. Why? Because the pre-teen ages are interested in that..though yes, there is a point to it being overdone. I wanted to see that Naturally Sadie show..until I saw it. I thought it would be a better show...it's not, it's dumb. It's a remake of That's So Raven and Lizzie McGuire in confusing form.
In short, I dislike the entirity of Disney Channel, I only watch for the movies and to fulfill my unnatural curiosity.
